What is the point of digging caissons? What is caisson construction

There is nothing particular about this, as long as you dig a little deeper, there will be water coming out, and generally speaking, it is better to be a little straighter and less likely to collapse.

You have to choose a good address for this, otherwise you won't be able to get through, and it will lead to the exercise of rock formations at that time. If you are satisfied, please give a trouble, I wish you a happy life!

Sitting in a house facing north and facing south, digging a caisson in the northwest garage is not good, affecting feng shui.

Before opening the well, it is necessary to pay tribute to the god of the earth, and when the water comes out, it is necessary to pay tribute to the god of water.

Caisson classification according to the shape of the caisson 1, according to the plane shape of the caisson Circular caisson: symmetrical shape, easy to excavate, sinking is not easy to tilt, but poor adaptability to the shape of pier and table section Rectangular caisson: adapt to the shape of pier and table section.

The importance of digging a caisson is that the deeper it is dug, the clearer the water will be.

First of all, the location of the award needs to be selected to determine that the groundwater is shallow and can produce water, and then there is that when you dig the well, you must be vertical, and the slightest deviation may collapse. It should be a large wellhead and a small bottom of the well.

Under normal circumstances, you are particular about digging wells, either 3 meters 3 or 7 meters, they are all different. Specification.

Sitting in a house facing north and facing south, digging a caisson in the northwest garage is not good, affecting feng shui.

The deeper the well is dug, the more attention should be paid to the danger of collapse at all times.

Digging a well is a particular thing, mainly to see how deep it is to find out that there is sewage, and then to see how deep it is to have water.

The most important thing about this kind of attention is horizontal and vertical, and there must be certain specifications.

What is the point of digging caissons? Chen Jing must be dug up with a sturdy safety and high-end.

If he used to be exquisite, it must be very exquisite, that is, if everyone is concerned, he may imagine that it is different.

The main method of ultrasonic detection is used.

The importance of digging caissons is very large, and it is necessary to consider the geological environment and mechanical conditions.

There should be nothing special about this.

Is there anything special about digging deep wells? The deep well is exquisite, and it is quite hidden from you to dig the well. You should consult someone who knows this before drilling a well.

What is the importance of the big deep well, it is better to stretch the neck draft, and there is nothing to pay attention to.

Is there anything particular about your ruling, pure of course is prized, and the quality is very good.

What is the point of digging caissons, borrow you to log in and I will consult again.

Is there anything special about Hua Chenjing? The scene is as it should be.

What is the point of digging caissons? I really don't know, I haven't done this, so I recommend consulting someone who knows.

Is there anything special about digging caissons? I feel that there is a certain amount of attention to this, but it is best to ask a professional about this.

Nerves, what's the point? If you dig a deep well, you must be particular, they often do this, they all know, you can ask.

There must be a particular point in it, when will the water come out of the water where you dig and the depth you dig?

Well, I still have a lot of attention to digging deep wells, and we should all choose according to local needs, and this place is different.

I said that I have been digging wells, if there is anything particular, you can look at the instructions for digging wells, so what kind of eyes do you get?

I suggest that you go to a professional to help you identify what is important, and you can't infer it yourself.

The caisson construction will be on the ground in advance with a wellbore-shaped structure made of reinforced concrete as the support of the foundation pit wall, under the protection of the well wall, with machinery and manual digging in the well, and in its own weight sinking into the soil of the structure called caisson. In essence, it is the construction process of a structure that has been poured in advance on the ground and sinks to a certain depth through excavation to become an underground structure.

The components of the caisson are, the wellbore is the wall of the caisson, is the main component of the caisson, he as the enclosure structure and foundation of the underground structure, to have enough strength, its internal space can be fully utilized. The wellbore sinks by its own weight or the frictional resistance of the soil around the wall of the external force, and the wellbore is generally made of materials such as reinforced concrete, brickwork or steel.

The cutting edge is in the lower part of the caisson wellbore, and the shape is an inner edge ring knife, which is used to reduce the resistance of cutting soil at the lower end of the caisson wall when the wellbore sinks, and is convenient for the operator to dig the soil close to the outer wall of the caisson blade foot. The height of the blade varies depending on the hardness of the soil, and should be heightened appropriately when the soil is soft. There is a horizontal support surface at the upper end of the blade foot, commonly known as the blade foot tread.

partition walls, pilasters and beams. In order to meet the requirements of caisson use, increase the rigidity of the wellbore and prevent the sudden sinking of the wellbore in the construction process, generally set up a transverse longitudinal partition wall or beam in the larger caisson wellbore, and the bottom elevation of the partition wall is 500 1000mm higher than the blade foot tread.

The bottom plate, the bottom plate of the caisson is in the lower part of the wellbore, which is the bottom of the caisson. In order to enhance the connection between the well wall and the bottom plate, the groove groove connecting the bottom plate is left on the upper wellbore wall of the cutting edge, and the depth is 100 200mm.

The characteristics of caisson method construction are that there is no need to set up pit wall support or sheet pile wall in the process of caisson sinking, compared with the open cut method, the construction is simplified, can be made on the spot, the required machinery and equipment are simple, used as an underground building, the cost of its monomer is lower, the concrete of the main part is poured on the ground, the quality is easier to guarantee, and the overall stiffness is also larger.

Second Construction-Municipal-Knowledge Points-What is a caisson.

Caisson A device that collects sewage.

The caisson caisson is a well-barrel-shaped structure, which is excavated in the well, and sinks to the design elevation after overcoming the frictional resistance of the well wall by its own gravity, and then passes through the concrete bottom and fills the well hole, making it the foundation of the bridge pier or other structures. It is generally used in the construction of foundation pits of large bridge piers, sewage pumping stations, large-scale equipment foundations, civil air defense shelters, shield assembly shafts, underground lanes and station hydraulic foundation construction enclosure devices.

Basic Information. Chinese name: Shenjing.

English name: open caisson, well-sinking, sink definition: well-barrel-like structure.

Pros: Safe.

An overview of a device for collecting sewage, built on the foundation pit, sinking to a certain elevation with a long-arm excavator, and then connecting it with a pipe jacking pipe, making a good launder, covering the lid can be, the cover is generally cast-in-place, the compactness is good, and the prefabrication period is short.

It's a way to push someone into a well and kill them.

In addition, it is also an engineering term.

A device for collecting sewage, built on the foundation pit, sinking to a certain elevation with a long-arm excavator, and then connecting it with a pipe jacking pipe, doing a good job of launder, covering the lid can be, the cover is generally cast-in-situ, the compactness is good, and the prefabrication period is short.

Caisson foundation is a type of underground structure and deep foundation constructed by caisson method. It is to make a well-barrel-like structure (caisson) on the surface of the ground, and then under the enclosure of the well wall, through continuous excavation from the well, the caisson gradually sinks under the action of its own weight, and after reaching the predetermined design elevation, the bottom is sealed to construct the internal structure.

It is widely used in the foundation of bridges, chimneys and water towers; Pump rooms, underground oil depots, pool shafts and other deep well structures and shield or pipe jacking working wells.

Technically it is more stable and reliable, the amount of excavation is less, the impact on the adjacent buildings is relatively small, the caisson foundation is deeply embedded, the stability is good, and it can support a larger load.

Caisson is a widely used structural form, generally in the form of circular or rectangular reinforced concrete structure, which can be used as a pumping station water intake structure, or as a foundation form. As far as the caisson is concerned, the caisson is first constructed in sections and sections at the original ground elevation position or the relatively shallow elevation position (the bottom is made into the cutting edge of the cutting surface), and then the soil body at the bottom is excavated inside, so that it sinks vertically along the design axis, and finally sinks to the design elevation, and then carries out drainage and sealing the bottom, and carries out a construction method of bottom plate construction.

The caisson construction method is to be located in a certain depth of the underground building or building (structure) foundation, now above the ground to make, to form a well-like structure, and then continue to dig in the well, with the help of the weight of the well body and gradually sink, sink to the predetermined height, after the bottom is sealed, the construction of the well floor, beams, floors, internal partition walls, roofs and other components, and finally form an underground building or building foundation.

The construction sequence is as follows: pouring the first section of the well wall - > connected to the high well wall - > initial sinking - > excavation and sinking, side connection to the high well wall - > sinking to the design elevation - > back cover - > caisson internal construction.

Caisson is to dig a well below the ground, and there are many construction techniques. According to different needs, choose different construction techniques.
